By the support- 0 accompanying drawings, and. particularly ing of the bottom 6 in the manner as herein o pointed out in the claims hereunto appended. set forth a space or chamber 10 is formed be In describing the invention in detail refertween the said bottom 6 and the bottom 4 of ence is had to the accompanying drawings, the tank. This chamber 10 is adapted to reforming a part of this specification, wherein ceive the dye liquor as it leaves the deflector 5 like reference characters denote correspond- 11, mounted upon the bottom t, the deflector 5 ing parts throughout the several views, and 11 communicating with the supply-pipe for in which I the dye liquor to be hereinafter referred to. Figure 1 illustrates asectional elevation of The perforated bottom 6 of. the receptacle 5 the apparatus. 'Fig. 2 illustrates aplan of a is provided with a series of ring-bolts 12, to 50 portion of the apparatus; and Fig. 3 an elewhich are connected the lifting-chain s 13.

These chains are adapted after the material has been operated upon to be attached to a suitable hoisting device, so that the finished material can be lifted out of the receptacle 5 and transported to any point desired.

The reference character 14 denotes a compression-plate, which is provided throughout with perforations 15. The plate 14 also acts as a closure for the receptacle 5 and operates within the receptacle. The plate 14 is reinforced by means of angle-iron 16 and is provided centrally with a sleeve 17, which permits of the mounting of the plate 14 upon the compression-screw 18. The screw 18 is suitably connected at its lower end to the bottom 4, as at 19, and extends upwardly through the bottom 6 of the receptacle 5 and projects at its upper end above the collar 17, the latter being connected, by means of a spider 20, to the plate 14. The latter has also connected thereto a plurality of ring-bolts 21, to which is adapted to be connected a suitable lifting means,sothattl1e plate 14 can be removed from within the receptacle 5. The plate 14 is adjusted when arranged within the receptacle 5 by means of the adjusting-nut 22, mounted upon the outer end of the screw 18. It will be evident that by moving the nut 22 down the screw 18 the plate 14 will be carried therewith, thereby compressing the material which has been previously placed upon the bottom 6. When the material to be treated is placed upon the bottom 6, the lifting-chains 13 are arranged so that they will extend up the side and on the top thereof, as shown in Fig. 1.

The diameter of the receptacle 5 is such that when the said receptacle 5 is arranged within the tank 1 it will form in connection with the tank 1 a chamber 23, which communicates with a primary supply-pipe and also a suction-pipe, to be hereinafter referred to. Arranged at the bottom of the chamber 23 is a heating-coil 24 'for heating the dye liquor. To the bottom 4 of the tank 1 is connected, as at 25, the lower ends of a plurality of vertical rods 26', which extend through the chamber 23 and have their upper ends screwthreaded, as at 27. Each of theserods carries a collar 28, having formed integral therewith a downwardly-extending dog 29, which is adapted to project into the receptacle 5 and engage the plate 14 for holding the said plate 14 down after the material has been compressed. The dogs 29 prevent the bulging upwardly ofthe plate 14. The dogs 29 are secured in their retaining position or their engaging position with the plate 14 by means of the adjusting-nuts 30, mounted upon the 26 to a suitable height the dogs 29 can be swung outwardly and clear of the receptacle 5, so that there will be nothing to prevent the lifting out of the plate 14 and the removal of'the perforated bottom 6, carrying the material which has been treated. Projecting from the inner face of the tank 1, as well as being suitably secured to the tank 1, as at 31, is a series of braces 32 for the rods 26.

The tank 1, at one side near the top thereof, has communicating therewith a primary supply-pipe 33 for the dye liquor. The pipe 33 is connected by the coupling 34 to a pipe-section 35, which communicates with a suitable valve mechanism 36, which has also communicating therewith a feed-pipe 37. The latter is in communication with a suitable reservoir, so that when the valve 36 is opened the dye liquor will pass from the reservoir up through the pipe-section 35 into the primary supply-pipe 33 and be discharged into the tank 1 until the receptacle 5 is'completely submerged with dye liquor. The height of the receptacle 5 is not as great as that of the tank 1. Consequently it will permit of the receptacle 5 being submerged by the dye liquorwhen it is supplied to the tank 1. Communicating with the chamber 23, at or near the lower end thereof, is a suction pipe formed of three sections 38 39 40. These sections are connected together by the T- coupling 41, in which operates a three-way valve 42. The section 39 of the suction-pipe communicates with a pump 43, which is operated by any suitable prime mover, and, as shown, a steam-engine 44. Communicating with the bottom 4 of the tank 1 is the auxiliary supply-pipe 45 for the dye liquor, and the auxiliary supply-pipe is formed of the pipe-sections 46, 47, 48, 49, and 50. The section 46 communicates at its upper end with the deflector 11 and at its lower end is connected by means of the coupling 51 to one end of the section 47. The sections 47 and 48 and the section 40 of the suction-pipe are connected together by means of the T-coupling 52, in which operates a three-way valve 53. The sections 48, 49, and 50 are connected together by means of a T- coupling 54. The section 49 communicates with the pump 43 and the section 50 communicates with the valve mechanism 36 for establishing communication between the said section 50 and the sections 35 and 37 of the primary supply-pipe.

In Fig. 2 of the drawings the perforated bottom 6 of the receptacle 5 is shown connected to a suitable hoisting device 55.

The deflector 11, mounted upon the bottom 4, is adapted for evenly distributing the dye liquor when it is fed or supplied to the tank 1 by the auxiliary supply-pipe. The height of the deflector llis such as to leave a suitable space between the bottom 6 of the receptacle 5 and the top of the deflector. The deflector 11 is provided with the side openings 11 for the discharge of the dye liquor.

The operation of the apparatus is as folluv lows: Theplate 14 is removed and the receptacle5 filled, say, with aboutfive hundred pounds of raw cotton as taken from the bale without any previous opening or handling. The lifting-chains 3 are then arranged in po sition, as shown in Fig. 1. The plate 14 is then replaced and the whole'mass compressed by means of operating theadjusting-nut 22, which forces the plate 14 downwardly. This operation is continued until the proper state of compression of the material to be treated is reached. At this stage the plate 14 is retained in its adjusted position by bringing into engagement therewith the dogs 29,which are held in their engaging position by means of the nuts 30. The tank 1 is then supplied with dye liquor through the medium of the primary supply-pipe and the said body of dye liquor is heated to a suitable temperature by means of the steam-coil 24. e The quantity of dye liquor is such that it will completely submerge the receptacle 5 and is of such quantity that when it is drawn ofiand forced through the material to dye it there will always be a suflicientquantity of the dye liquor in the tank 1 to prevent the ma terial being treated from coming into contact with the air. When the dye liquor has reached the proper degree of heat, the prime mover is started, which drives the pump 43.- The pump takes or draws the dye liquor from the chamber 23 through the suction-pipe, or rather through the sections 38 and39 of the suction-pipe, as the valve 42'has been set for such purpose. The pump then forces the dye liquor through the sections 49, 48, 47, and 46 of the auxiliary supply-pipe into the deflector 11. The dye liquor then passes out of the deflector 11, through the perforations in the removable bottom 6, through the material which is to be dyed, into the space formed in the receptacle 5 above the plate 14, then overflowing from said space into the chamber 23, then outwardly through the suction-pipe into the pump, and the operation continued as hereinbefore specified. The valve53 has been set so that the dye liquorwill be forced by the pump through the sections of the aux- V iliary supply-pipe in the manner as just men'- tioned.

It will be evident that the circulation can be reversed in a manner other than as set forth, and in which instance the auxiliary supply-pipe would form the suction-pipe and the primary supply-pipe become the auxiliary supply-pipe. This operation is as follows: The valves 53 and 42 are set. The setting of the valve 53 will establish communication between the section 47 of the auxiliary supply-pipe and'the section 40 of the suctionpipe. The setting of the valve 42 will establish'communication between the sectious-39 and 40 of the suction-pipe. The valve 36 is then set to establish communication between the hoisting device.

dye liquor is fed into the tank 1, thereby com-- pleting a perfect circulation, the dye liquor consequently having traveled in both directionsby the first operation herein described from the bottom to the top, and by the secondary operation herein described from the top to the bottom.

If it be necessary to force the dye liquorin but one direction to completely dye the material, this is continued the necessary time. The material is then washed, or if it be necessary to circulate the dye liquor in alternate directions to completely die the material this operation is continued the necessary time and the material then washed; but in either case it is necessary that the material be washed. The circulation of the washing medium is done in the same manner as the circulation of the dye liquor. After the dyeing and washing are completed the nut 22 is removed and the dogs 29 elevated and moved out of the path of the perforated plate 14. The perforated plate 14 is then removed by any suitable hoisting device, and the hoisting device is then connected with the chains 13 and the bottom plate 6, with the material thereon, lifted out of the receptacle 5 and transported to any suitable point desired.

The hoisting device 55 may be connected by a pipe 56 to the engine 44, so that the latter will not only be employed to drive the pump, but also be the means for operating that the hoisting device can be mounted upon suitable tracks, (not shown-,) so that the plate 14, as well as the plate 6 and the material, can be readily transported.

It is thought the many advantages of my] taken in connection with the accompanying drawings, and it will furthermore be evident that changes, variations, and modifications can be resorted to without departing from the spirit of the invention or sacrificing any of its advantages, and. I therefore do not wish to restrict myself to the details of construction hereinbefore described and as shown in theaocompauying drawings, but reserve the right to make such changes, variations, and modifications as come properly within the scope of the protection prayed.
